SPECIFICATION forming part of Letters Patent N 0. 709,096, dated September 16, 1902.

Application iiled January 21, 1902. Serial No. 90,681. (No model To all wiz/0m, it may concern:

Be it known that I, ADAM S. KIEFER, a citizen of the United States of America, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Valve Mechanism for Fluid-Supply Pipes; and I hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

This invention relates to improvements in valve mechanism for a Huid-supply pipe, and more especially to the combination, with a fluid-supply pipe, of a tubular valve-casing attached to and extending through and transversely of the said pipe and provided within the said pipe with a lateral induction-port in open relation with the interior of the pipe, a discharge-oriflceformed in the valve-casing externally of the fluid-supply pipe, a passageway connecting the said orifice with the aforesaid port, a suitably-applied valve for controlling and regulating the flow of luid through the said passage-way to the dischargeorilice, and another valve for regulating the supply of iiuid to the receiving or port-connecting end of the said valved passage-way.

The object of this invention is to provide valve mechanism especially well adapted for supplying a iine stream of fluid-such, for instance, as gas and vaporto the heatingburner of a stove or furnace, to avoid the use 'of a needle-valve in the discharge-orifice, so as to leave the said oritice unobstructed, and

`thereby avoid spraying or scattering of the iiuid from the said orifice, to render the construction and arrangement and assemblage of the parts convenient, to positively prevent turning or displacement of the Valve-casing relative to the fluid-supply pipe, to effectually avoid leakage, and to provide mechanism which is not liable to vget Aout of order and whose component parts are readily separable for repairspand cleaning purposes.

With this object in View and to thc end of realizing other advantages hereinafter appearing, the invention consists of certain features of construction and combinations of parts hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure I is a top plan of a portion of a Huid-supply pipe provided with valve mechanism embodying my invention. Fig. II is a vertical section on line II Il, Fig. I, looking in the direction indicated by the arrow. Fig. III is a vertical section on line III III, Fig. II, looking in the direction indicated by the arrow.

Referring to the drawings, a, designates a Huid-supply pipe, and b a valve-casing which extends centrally through and transversely of the pipe a. rlhe valve-casingb, :as shown, extends vertically through the pipe a, which is apertured or perforated at the top and bottom, as at c, to accommodate the vertical extension through the pipe a of the casing b. The valve-casing b is tubular and within the lower portion of the pipe a has a lateral induction -port d, which extends laterally through the casing and is in open relation at each end with theinterior of the pipe a. The valve-casing l) extends below the pipe a and below and externally of the pipe has a discharge-orice e, and the said casing is provided interiorly with an angular passage-way f, which connects the orifice c with the port d centrally between the ends of the said port, and a suitably-applied valve g controls continuity in the passage-way f at the angle in the said passage-way and controls and regulates the passage of fluid through the said passage-way to the orifice e. The valve-casing b is internally screw-threaded, as at h, above the port d, from the said port to the upper extremity of the casing, and a correspondingly externally-threaded screw 7c is screwed from above into the said casing and has a downwardlypointing conical lower valveforming end l and extends transversely of the port d into the passage-wayf. The valve Zis arranged to regulate the supply of fiuid from the port d to the receiving end ofthe passage-way f. The screw 7c is provided in its outer end with a recess m for accommodating the application of a screw-driver, and the screw is arranged entirely within the valve-casing, so that the screw does not project upwardly beyond the upper extremity 0f the said casing. Thefvalve-casing b extends a suitable distance above the pipe a, and is screw-threaded externally, as at n., above the IOO said pipe. A correspondingly internallythreaded cap o is screwed onto the upper end of the valve-casing, and a washer or packing p is arranged within the said cap and is held by the cap tightly against the upper end of the valve-casing and forms a fluid-tight joint between the valve-casing and the said cap. A clamping-member-forming collar r loosely embraces the valve-casing b at the upper side of the pipe a, and a packing-forming washer s snugly embraces the said casing between the inner end of the said collar and the said pipe, and a nut t engages threads n of the valve-casing at the outer end of the collar or clamping member r and causes the said member r to tightly bear against the said pipe. The collar r has two lips or flanges r arranged at opposite sides, respectively, of the valvecasing and extending somewhat downwardly and partially embracing and conforming to the pipe a, and the washer s has the dimensions required to extend between l[he said lips or iianges and the pipe. The valve-casing b is provided at the under side of the pipe d with an external annular clamp-memberforming flange u, and a packing forming washer tu is interposed between the inner side of the said flange u and the said pipe, and obviously the turning of the nut t in the direction and to the extent required to effect a tight engagement between the movable clamping member or collar r and the pipe results in drawing the clamping-flange u and the washer w tightly against the under side of the said pipe. The washer w snugly embraces the valve-casing b, and the flange u and the said washer extend somewhat upwardly and partially embrace and conform to the pipe a.

It will be observed that by the construction, arrangement, and assemblage of parts hereinbefore described the employment of a needle valve in the discharge orifice e is avoided, and consequently there is no spraying or scattering of the fiuid discharged from the said orifice; that regardless of the pressure of the fluid in the pipe a the supply of fluid to the passage-way f is readily regulated by properly manipulating the screw 7c upon the removal of the cap 0 and the washer or packing p; that the parts are readily assembled and as conveniently and quickly separated for repairs and cleaning purposes; that there is no liability of displacement of any of the parts when assembled; that the clamping members r and u and their partially ernbracing the pipe d positively prevent turning of the valve-casing.

The valve-casing is cut away externally, as at x, interiorly of the pipe a, adjacent the sides of the said pipe, (see Fig. 11,) so as to obstruct as little as possible the passage of iiuid around the valve-casing within the said pipe.

What I claim isl. The combination, with a fluid-supply pipe, of a tubular Valve-casing extending through and transversely of the said pipe and provided, within the pipe, with an inductionport communicating with the interior of the pipe, which valve-casing is provided externally of the pipe with a discharge-orice and has a passage-way connecting the said orifice with the aforesaid port; a valve in the said passage-way 5 another valve arranged to regulate the supply of fluid to the said passageway from the aforesaid port; two clamping members arranged externally of the pipe and directly opposite each other and partially embracing the pipe, packing-forming washers surrounding the valve-casing and interposed between the clamping members and the pipe, and means for causing the said clamping members to bear against the pipe.

2. The combination, with a fluid-supply pipe, of a tubular valve casing extending through and transversely of the said pipe and provided within the pipe, with an inductionport communicating with the interior of the pipe, which valve-casing is provided, externally of the pipe, with a discharge-orifice and has a passage-way connecting the said orifice with the aforesaid port; a valve in the said passage-way; another valve arranged to regulate the supply of fluid to the said passageway from the aforesaid port; two clamping members arranged externally of the pipe and directly opposite each other, with one of the said clamping members in the form of an annular flange formed upon and partially embracing the pipe, and with the other clamping member' in the form of a collar embracing the valve-casing and having lips or flanges partially embracing the pipe; packing-forming washers surrounding the valve-casing and interposed between the clamping members and the pipe; and a nut screwed onto the valve-casing at the outer end of the collarforming clamping member, substantially as and for the purpose set forth.
